FOR CC2520 RF ZIGBEE I NEED QFN PACKAGE footprint(28 PIN) for orcad 9.1. i saw it in yahoo orcad exchange group but it is not match for CC2520 IC, b'coz it has 28pin + centre pad(thermal pad is ground pad). if i gnd this pad, error occurs(5mils trace only used for routing). if any one designed or have it, plz send it to me.plz very urgent.
 

Look for and learn the IPC-7351 format and data, and do a search for
"the cad library of the future".
And DITCH imperial measurements, metric is better:)
